After being murdered, Makina Hoshimura turns into a "living corpse." Armed with dual MAC-11 submachine guns, she must kill 108 other corpses in order to gain entry into heaven. She is assisted in this task by Keisei Tagami, a Buddhist priest with links to an anti-corpse group known as the Kougun Sect. Her ultimate goal is to avenge the death of her family, by destroying the corpses known as the Seven Stars.
